' `The arrangements and methods which have become known fordyeing of loose yarns or yarnsin bobbins require special devices, a greaterlnumber of apparatus and supply conduits., and special packing systems as vfor instance boxes, rakes and the like. These, for the greatest part very complicated 1 installations do not permit of a rational working, as not only the changing to another colour, but also the repacking requires much time and greatV skill of ,the attendants; There exists the further inconvenience that the dyeing oflsmaller quantities, as forinstance for testing purposes,.is far too ex-v pensive owing to the large installations, and that larger quantities cannot be dyed perfectly and uniformly, as great quantities exclude the individual effect of the dyeing which is possible for smaller quantities. A

The invention relates to a machine for dyeing, bleaching and othertreatments vofvloose lyarns or yarns in lbobbins, which unite all the arrangements necessary for dyeing, washing and drying and consequently exclude the above mentioned inconveniences. The machine works, so to say, according tothe large batch system and dyes nevertheless perfectly and uniformly smaller or larger quantities,

owing to its individual working manner.

According tothe invention at least two vessels communicate with each other, elements kfor receiving the material, conveying elements forv the working media and collecting elements for collecting and returning the media'into vone of the vessels being provided.

.The whole installation is arranged so that the procedures necessary for the moistening, washing and vdrying can be carriedout consecutively in any desired succession without the necessity of discharging the dye bath wholly from the machine.

embodiment of the invention is illustrated by way of example in the accompanying drawings in which: f

Fig. 1 is a vertical section, and 1 Fig. 2 'is a top plan view of the machine.v Fig. 3 shows in vertical section a holding element with a bobbin.

A Fig. 4 is a similar view of a slight modi- 391,106, and in switzerland :une 12, 1929.

cationi Showing a' hlding element with-a i perforated drum lled with loosematerial.v f YThe machine consists of a circular frame '1 with feet 2. yIn the frame l'two' vessels 3,4-

.5.5 lower vessel 4 has a downwardly curved botare arranged, the one above the other. The

of the vessels level indicators 11 are arranged. The vat is closed by a double cover plate 12 fixed on the frame 1 by means' of-screws as shown in Figures 3 and4. In the space between the two cover 'plates a driving spur wheel 16 is located, keyed on a driving axle 15 and having a diameter approximately of the diameter oftheves'sels 3, 4. e This spur wheel 16v meshes with V,around the same. Y Y

The Vdriving motor or engine` 14 can be adjusted by a governor'of known type, which isnot shown, to any number of revolutions, the revolving speedbeing selected according to the desired color tone andto the consistence lpinions 17 arranged of the bobbin and the diameter of the same;

or according to the density of the layers of` yarn in the drum,

Supply tubes 19 arranged aroundthe driving wheel and journaled in the cover plate, (preferably by means of ball bearings) ex` tend intothe lower vessel orcontainer 3. In each of thesetubes 19 a rotatable conveying Vscrew 20 is arranged which revolves with its tube 19 'and serves as a regulator. In the form-shown in Figure 1 the pinions 17 are lrigidly'l'ixedon saidtubes 19, and a. head piece or spindle 21 of frusto-conical forml is mounted on the upper end ofeach tube and is designed to carry abobbin 22 or dyeing drum 23. It will be seen that a bobbin is .shown at the leftof Figure 1 and a dyeing drum at the right, this being to illustrate that either may be used. At the joint between the head piece 21 and the tube 19 a conveying space 24 is arranged through which channels 25, 26`

respectively extend, which lead `towards the circumference of the head piece or to the inner side of the bobbin or drum. In the form shown in Figure 4, thestr'ucture is quite similar but each tube carries a head piece or spindle 21 which is built up of annular sections in such manner that intervals or spaces 26^-are formed ,between adjacent sections.

The drums 23 are preferably made of perforated sheet metal or wire gauze and designed to hold loose material. The drums are used for instance for dyeing spools consisting of cardboard-sleeves containing loose yarn or raw material which, owing to its shape or property, cannot be mounted on the head iece. l; p Glass cylinders 27 enclose the head pieces, bobbins and drums and from each glass cylinder 27 extends a discharge tube 28 intoA the vessel 4. The dye bath thrown off bythe bobbin or drum is collected in the glass cylinder and returned through the discharge t'ube 28 into the vessel 3. The glass cylinders enable observation of the dyeing process, so that any disturbances which should occur can be instantaneously regulated.` Y l y The Vmachine is further fitted with vacuum meters, pressure meters, thermometers, supply conduits, discharge conduits and, if necessary, withpumpsfwhich, being known, are not shown on the drawings.

A dyeing operation will be been poured into the lowervessel 4, the electric heating bodies l() are lswitched in to boil thebath.` Into the upper vessel 3 washing water is filled to which, if n-ecessarys'uitable substances are added. This washing water is conveyed through the rotating tubes 19, to the ,the vessel 4to the desired temperature is theirforced by pressure or vacuum through the connecting tube 6 into the vessel 3.

, According to the consistence or according to the desired color shade, the material is rotated by the-regulation of the driving mech- A anism at a number of revolutions in accordance withthe diameter of the bobbin or the density ef the yarn layers in the drum, the rotation being continued until the desired color shade has been obtained.` The conveying screws 20 ensurethat always the same quantity of dye bath is conveyed to the bobbins or drums. After the dye bath has been returned into the lower vessel 4 the bobbins y hereinafter briefly described. vAfter the dye bath has or the material in the drums are washed in the manner above described, or they are centrifugally dried by rapid rotation.

The d ve bath in the vessel 4 is boiled again so that'tlie upper vessel 4 is heated, wh-ereby the drying of the material is accelerated. rlhe dyed bobbins or the drums with the dyed material are removed after kthe drying, and fresh bobbinsor drums inserted. Y i

The machine can hold a considerable number of bobbins so that a greateiiiciency is ensured, the dyeing remaining'jhowever,'indif vidual for every single bobbin, soA that 'a perfect and uniform dyeingis obtained.

For the production of samples only certain bobbins being left loose? by, for 1n stance, unscrewing the set screws y 17f which are shown as one conventional/method of securing these pinions on their'tubes. AThe observations made during the sampling and the numbers of revolutions used for the dyeing ofthe samples will be useful during vthe dyeing of great quantities so that absolutel uniform goods are obtained. y

' For the electric heating any other suitable heating may be substituted.

Obviously, the dye bath may be replaced by bleaching or other baths such as are used in treating yarn and the like, the operation being carried'out in the manner described in relation to dyeing.

' We claim: Y i

1. A machine for dyeing, bleaching and the like of loose yarns or bobbins, comprising upper and lower vessels, the lower for heating the dye bath and the upper for washing and drying a double cover plate on said upper vessel, rotatable tubes extending from isaid upper vessel to above said cover plate kthe progecting portions of said tubesde-` signed to hold bobbins or perforated drums d with loose materia-l, driving means for rotating said tubes, means connecting said lower vessel to said upper, vessel, aY collecting prising in combination with the driving mechanism, means for regulating this driving mechanism for driving any number offlzo the total number of bobbins.

3. A machine, as specified in claim 1, com,- prising in combination with the rotatable tubes holding the bobbins Yor perforated drums on the upper end, a conveying screw?" in the tube for conveying permanently uniform quantities of dye bath to the inner side of the bobbin or drum. v

4. A machine as specified in claim 1, in

whichthe several tubes may be rotated seglass cylinder for each bobbin or drum, said-'110 lectively, the treating media being supplied to the bobbin or drum at'the center of the material to be treated and forced through the same in outward direction by the centrifugal force.

In testimony Whereor` I affix my signature.
